abstract = {Measurement of the ultra-rare $K^+\to\pi^+\nu\bar\nu$ decay
at the NA62 experiment at CERN requires high-performance
particle identification to distinguish muons from pions.
Calorimetric identification currently in use, based on a
boosted decision tree algorithm, achieves a muon
misidentification probability of $1.2\times 10^{-5}$ for a
pion identification efficiency of 75\% in the momentum range
of 15-40 GeV/$c$. In this work, calorimetric identification
performance is improved by developing an algorithm based on
a convolutional neural network classifier augmented by a
filter. Muon misidentification probability is reduced by a
factor of six with respect to the current value for a fixed
pion-identification efficiency of 75\%. Alternatively, pion
identification efficiency is improved from 72\% to 91\% for
a fixed muon misidentification probability of $10^{-5}$.},
